No Software Required: Raspberry Pi Uses Electromagnetic Waves to Detect Malware

I couldn't find this already posted, and wasn't sure where to post it.

Not clear if this is an early April Fools joke or what. Does this even seem feasible?

The end result is a system with a malware-detection accuracy of 99.82%, which could prove invaluable to malware analysts.

Something like a PC with very varied operating states normally likely it wouldn't work with.

Certain operations produce very repeatable and consistent power draw traces from an embedded processor. AES is incredibly trivial to discover the keys for using differential power analysis

That certainly helps clear it up for me. In summary: they are scanning systems with a fairly static operation. In other words, any system will run within certain thresholds regarding heat, power consumption, things like that. So, if there is a [calculated] variation in monitored items, it will trigger an alert. Does that sound accurate?

I don’t know why the articles specify “malware”… this type of scan would be useful for detecting potential hardware failures or other unexpected loads. Pretty cool if you ask me.

Thanks for the feedback!
